Facebook accused a group of hackers in Vietnam of spreading malicious code and stealing information from users of the platform.
In its December 10 announcement, Facebook said it was cracking down on independent hacking groups in Vietnam and Bangladesh. These groups are said to use the Facebook platform to spread malicious code, steal user information, and hijack accounts.
According to Facebook, a group of hackers in Vietnam used three main types of attacks, including social engineering, attacks through Android applications, and attacks by spreading malicious code on websites.
Social engineering is a form of non-technical attack that hits the psychology of the user to obtain information. Facebook said that Vietnam hackers have created fake characters and organizations on social media, creating legitimate cover to reach the target they want to attack. Hackers also create pages to attract followers and then trick users into installing malware.
The second method is through Android smartphones. Hackers create apps on Play Store, lure users to install the target. That way, they control their equipment. Furthermore, this group also attacked Facebook users by spreading malicious code through websites. This could be a website they created or an existing but compromised website to install malicious code. Another form that is reported is through abbreviated links.
Facebook says it has been following this group of hackers for years. In the latest indictment, the world’s largest social network said it found a link from this hacking group to CyberOne, an information technology company based in Ho Chi Minh City. However, CyberOne Group recently responded Reuters via the fan page that are not related to the previous hacker group. The fanpage of this unit later disappeared on Facebook.
Facebook also accused two hacking groups called DoN and CRAF in Bangladesh of compromising the accounts of users of the social network. These groups use Facebook’s reporting function, make accusations of phishing, intellectual property infringement, nudity, terrorism … which makes the victim’s Facebook account violate the community policy of the network. social and blocked.
This group is also said to occupy the Facebook account of the administrator of the main fan pages, remove the remaining administrators, and then deactivate the fan page. This attack was assessed by Facebook as intentional. Hackers in Bangladesh hacked email, hacked users’ devices, and took advantage of the Facebook account recovery process.
Facebook is taking a number of steps to prevent the actions of hacker groups, such as removing Facebook shared links, removing group accounts, and notifying users about the attack.
The expert of this social network advises users not to click on suspicious links, not to download software from untrustworthy sources.
